AI memory bottleneck spurs HBM, CXL, and specialized chip innovations

The AI industry is grappling with a significant 'memory wall' bottleneck, where GPU processing power outstrips memory bandwidth and capacity. This challenge is exacerbated by the increasing demands of training large generative AI models and the growing need for edge inference and agentic AI. Solutions like High Bandwidth Memory (HBM), Compute Express Link (CXL), and specialized on-processor SRAM meshes are being developed to address these limitations, though they introduce new challenges in supply, cost, and thermal management.
